Abstract
A cooling device includes a number of cooling tubes arranged in parallel such that a first cooling fluid and a second cooling fluid can flow in the cooling tubes. A tank communicates with the cooling tubes to allow the first cooling fluid or the second cooling fluid to flow through the cooling tubes. A diaphragm is located inside the tank to separate the tank into a first space allowing the first cooling fluid to flow therein and a second space allowing the second cooling fluid to flow therein. The diaphragm is coupled to the tank to be rectilinearly movable in a direction of an arrangement of the plurality of cooling tubes.
